I know the US is a constitutional replublic, but there was a famous republique that did fall *coughs* Rome. But having the head of state nad the head of government the same there is draw backs. For example he could pass bill that benefit him (obviously they would have to be pass by congress), but also it makes for a more independant country. the reverse is true about Canada's government *forgets name ( constitutional democracy, or maybe monarchy)* Also unfretted capitalism COULD lead to corporations having too much of a strong influence of the government. that is why I think that politicians shouldn't have ANY affliation with a corporation, buisness or etc... For it could influence his decissions, the head of state and government both should be neutral, thinking only for the best of their people, and not personal profit. So in my subjective opinion, capitalism has flaws too. yes, maybe communism is a meme, an idea that continues to pop up through out history. In my POV an ideal/perfect government is meme, and is unattainable for there is nothing perfect ever created by humans.
